关于同时求解多项式所有二次因子的迭代解法

Iterative Method For Simultaneously Finding All Quadratic Factors of A Polynomial

郑士明［６］，叶贻才［７］分别给出一种求多项式所有二次因子的迭代解法。本文给出另一种迭代解法，且证明本文的迭代法，郑立明［６］和叶贻才［７］对给出的选代法都相当于对系数的牛顿法，最后给出一些数值例子。

be a polynomial with real coefficients f Zheng Shi-ming[6] and Ye Yi-cai[7] each gave an iterative method for finding all quadratic factors simultaneously. In this paper we give another iterative method, and prove that this method and those of Zheng Shi-ining[6] and Ye Yi-cai[7] are all equivalent. Finally, we report some numerical results.
